[Machine] Fasting on Arafah expiates the sins of the year, as well as the year that follows it. Fasting on Ashura expiates one year of sins. Abdullah said, my father did not recommend it to us, and it is a recommended act.
صِيَامُ عَرَفَةَ يُكَفِّرُ السَّنَةَ وَالَّتِي تَلِيهَا وَصِيَامُ عَاشُورَاءَ يُكَفِّرُ سَنَةً قَالَ عَبْدُ اللهِ قَالَ أَبِي لَمْ يَرْفَعْهُ لَنَا سُفْيَانُ وَهُوَ مَرْفُوعٌ
